4. Which reasons are the best choices for explaining why the amounts of oxygenated hemoglobin decrease as altitude increases. A. The decreased partial pressure of oxygen at higher altitudes reduces the amount of saturated hemoglobin. B. Equilibrium binding constants of oxygen to hemoglobin decrease at higher altitude reducing the amount of saturated hemoglobin. C. Not being acclimated to higher altitudes keeps the percentage of oxygenated hemoglobin lower than when acclimated. D. Fewer bound oxygen molecules reduces the supporting impact of cooperative binding, thus lessening the amount of fulling oxygenated hemoglobin.
